"I have ordered the Attorney General to take the investigation under his personal control, because there are still a lot of questions remained," - said Poroshenko.

The President also ordered Arsen Avakov, the Minister of Internal Affairs, to make every effort to ensure law and order on the streets of Kyiv and in Ukraine in general to keep the situation under the control.

"It is unacceptable that someone broke into the building and set fire. I'm sure that this has nothing to do with the patriots. Today is no less, and even more damaging Ukraine than any contacts with provocateurs," - said Poroshenko.

At the moment, the protesters are installing the tents near the building of the TV channel on Dmytrivska street. Law enforcers do not interfere in the process. Now four tents are already installed.
